Hi Dave,
I enjoyed reading your article even though I am not in the recording business. At least I know how complex it is and the science is really good to understand. I stumbled on your article as I was doing some general research on hearing as we are in the digital signal processing business. We use complex near real-time algorithms to process inputs from bluetooth headset devices, handsfree carkits, multiple microphone arrays, etc to reduce the noise, establish direction of sound arrival, cancel out echoes, etc. We have developed a handsfree carkit the size of a mobile phone which can output 95dB without the acoustic feedback even though the mic is on the same box. I learned a lot, although not fully understanding everything but believe that there's a lot more to understand to make a great product, as with the skills required in making great recordings.
Cheers and thanks!

Philip

Hi Philip!

Thanks for your commnts and kind thoughts about my article on Equal Loudness Contours. It sounds like your are hard at work on some really interesting (and probably quite important) stuff.

Good luck, and keep up the good work.

Best regards,

Dave Moulton
